Inflammatory myofibroblastic tumor (IMT) of the genitourinary tract is a wellknown entity. The majority of the literature characterizes IMT of the bladder as a benign, slow growing tumor in children. We present two cases of aggressive IMT. Although rhabdomyosarcoma is more common, IMT should remain within the differential diagnosis for any bladder mass found in a child or young adult. The diagnosis of IMT is important in preventing unnecessary diagnostic procedures and guiding the appropriate treatment.
